This guide, which is the result of more than twenty years of work, presents the main groups of natural enemies of pests that can be found in green spaces. It is a support tool for managers and technicians related to pest control in urban ecosystems and also for the general public, interested in the biodiversity of fauna in the parks and gardens of our cities and towns.
Aimed at technicians and managers, the book describes the main groups of natural enemies that can be found in Catalonia and the rest of Spain. Information on the main groups of predators (insects, arachnids, birds, mammals), parasitoids (insects) and pathogens (nematodes, fungi and others) is provided. The most common species of each group are also indicated, with which pests they are related and in which habitats they can be found. A key for adult identification of the main natural enemies is included at the end of the guide.
